Abstract:

     We design a chlorophylla sensor based on the principle of fluorescence induction with fluorescence induction and weak signal detection. Experiment results show that linear relationship exists between the concentration of chlorophylla and the system measurement value,  linear fitting coefficient is 0.999. The instrument that is small and convenient for operation can achieve insitu monitoring of the concentration of seawater chlorophyll-a.

Key words: chlorophyll-a, fluorescence detection, insitu monitoring, weak signal detection
